Promoter sequences are DNA sequences that define where transcription of a gene by RNA polymerase begins. Promoter sequences are typically located directly upstream or at the 5' end of the ...

The clamping RNA polymerase ribozyme uses a specificity primer to recognize an RNA promoter. Once localized, the polymerase rearranges into a processive complex, capable of copying extended ...

In all species, transcription begins with the binding of the RNA polymerase complex (or holoenzyme) to a special DNA sequence at the beginning of the gene known as the promoter.Activation of the ...
